Characteristics for many 74X logic families

I got mail from several people expressing interest in this table of device characteristics for many 74X logic families. I have tried to include all of the common (and obsolete) families.  I have included a basic logic gate (74x00), a tri-state buffer (74x244), and a flip-flop (74x374). I have not included a latch, just to get a religious debate about the difference between a latch and flip-flop going :) To reduce confusion, here are the meanings of the mnemonics I have used:

tPLH - prop delay from low to high
tPHL - prop delay from high to low
VOH - logic level 1 output voltage
VOL - logic level 0 output voltage
VIH - logic level 1 input voltage
VIL - logic level 0 input voltage
IOH, IOL, IIH, IIL - similarly
tPZH - prop delay from high impedance to high 
tPZL - prop delay from high impedance to low
tPHZ, tPLZ - similarly
f - toggle frequency





Note that prop delays for the x374s are clock to Q times. I use the output and input voltages to calculate noise margins and output and input currents for DC loading calculations. I hope that ya'll find this table of use. Of course, forward any errors to me, but keep differences at the right of the decimal point to yourselves, I'm a digital guy and such minor errors don't affect me :) The vendor chosen for each family is given next to each device. The vendor was chosen by which data book I happened to pick up first. Enjoy. Thanks to Jarrod Johnson for typing it all in.
